Installing removable components
WARNING!
Long-time exposure to strong air flow might cause discomfort. As a best practice, do not stand close
to the air outlet vents while the device is operating. If you must be next to the device on the air outlet
vent side for an extended period, avoid the air flow or take other protective measures.
CAUTION:
•
As a best practice, connect power cords after installing all required removable components.
•
To ensure good ventilation, install filler panels in unused slots.
This section describes the installation procedures for the supervisor engine units (SEUs, also called
MPUs), interface modules, fan trays, and power supplies.
TIP:
Keep the chassis and the component packages secure for future use.
Attaching an ESD wrist strap
The device is provided with an ESD wrist strap. To minimize ESD damage to electronic components,
wear the ESD wrist strap and make sure it is reliably grounded before you install removable
components.
To attach an ESD wrist strap:
1.
Make sure the device is reliably grounded. For information about how to ground your device,
see "Grounding the device."
2.
Put on the wrist strap.
3.
Tighten the wrist strap to make sure it makes good skin contact.
4.
As shown in
, insert the ESD wrist strap into the ESD jack on the chassis.
CAUTION:
Use a multimeter to check the resistance of the ESD wrist strap. Make sure the resistance
reading between your body and the ground is between 1 and 10 megohms.
